METHOD FOR DETERMINING RADIO SIGNAL WEAKENING IN RADIO-TRANSPARENT HEAT-SHIELDING MATERIAL UNDER INFLUENCE OF INTENSE HEAT FLOWS USING RADIO SIGNAL Russian patent published in 2022 - IPC G01R29/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is used to determine the attenuation of a radio signal in a radio-transparent heat-shielding material (RTHM) under conditions of intense heat fluxes. The effect is achieved by the fact that the method consists in the fact that by means of a transmitting antenna a radio signal is emitted through the RTHM in a given frequency band, using a receiving antenna, a radio signal is received in the same frequency band, while simultaneously registering the initial characteristics of the radio channel and matching the transmitting antenna in a given frequency band, then during the entire time of exposure to intense heat flux and after it, the matching characteristic of the transmitting antenna and the attenuation of the radio signal in the radio channel in a given frequency band are measured, further, the difference between the measured characteristics of the matching of the transmitting antenna and the difference between the measured values ​​of the attenuation of the radio signal in the radio channel before, during and after exposure to intense heat flux is determined.

EFFECT: invention allows to determine the attenuation of the radio signal under the influence of heat fluxes.
